复制代码 代码如下:
class Program
{
//使用out后必须对变量赋值
public void TestOut(out int x, out int y)
{
x = 1;
y = 2;
}
//此时传进来的值分别为x1:10,y1:11,输出之后的x1的值为2

public void TestRef(ref int x, ref int y)
{
//引用剪剪那句话传进来的是猪,出来的可能是头牛(很精辟！)
x = 2;

}
static void Main(string[] args)
{
int x;
int y;
Program P1 = new Program();
P1.TestOut(out x,out y);
Console.WriteLine("x={0},y={1}", x, y);
//在使用之前ref必须对变量赋值
int x1 = 10;
int Y1 = 11;
P1.TestRef(ref x1,ref Y1);
Console.WriteLine("x1={0},y1={1}", x1, Y1);
}
}
